Ingredients for the Herb Crusted Prime Rib Roast
- Bone-In Prime Rib Roast: The star of the show, known for its marbled fat and deep flavor.
- Fresh Garlic: Brings robust, aromatic depth to the crust.
- Fresh Rosemary: Earthy and piney, it enhances the meat’s natural flavors.
- Fresh Thyme: Adds a subtle sharpness and blends well with rosemary.
- Kosher Salt: Essential for seasoning deeply and drawing out flavor.
- Cracked Black Pepper: Gives the roast a warm, slightly spicy kick.
- Olive Oil: Helps the herbs stick and promotes a crisp, golden crust.
These ingredients together create a flavorful, aromatic crust that complements the tenderness of the meat.
How To Make the Herb Crusted Prime Rib Roast
Step 1: Bring the Roast to Room Temperature
Remove the prime rib from the refrigerator at least 1.5 to 2 hours before cooking. This ensures even roasting.
Step 2: Preheat and Prepare
Preheat your oven to 500°F (260°C). Pat the roast dry with paper towels to ensure the crust adheres well.
Step 3: Make the Herb Paste
In a mixing bowl, combine minced garlic, chopped rosemary, thyme, salt, pepper, and olive oil. Mix until a thick paste forms.
Step 4: Apply the Herb Crust
Rub the herb paste generously over the entire roast, pressing it into the surface to coat evenly.
Step 5: Roast High Then Low
Place the roast bone-side down on the rack in the roasting pan. Roast at 500°F for 20 minutes to develop the crust, then reduce the oven to 325°F (163°C) and continue roasting for approximately 13-15 minutes per pound for medium-rare.
Step 6: Check Temperature
Use a meat thermometer to check for doneness. Aim for 120°F for rare, 130°F for medium-rare.
Step 7: Rest Before Slicing
Tent the roast loosely with foil and let it rest for 20-30 minutes. This step locks in the juices.
Step 8: Slice and Serve
Use a sharp knife to slice between the bones and serve thick, juicy cuts with your favorite sides.
Serving and Storing Your Prime Rib Roast
Serving:
Serve your Herb Crusted Prime Rib Roast alongside rich, complementary sides like creamy mashed potatoes, roasted vegetables, or a tangy horseradish cream sauce. Garnish with sprigs of fresh rosemary or thyme for a rustic touch.
For an elegant presentation, slice the roast tableside and let guests marvel at the juicy, pink center and herby crust.
Storing:
Refrigerate leftovers in an airtight container for up to 4 days. To reheat, wrap slices in foil and warm in a low oven (300°F) until heated through. Avoid microwaving, which can dry out the meat.
Leftover slices make delicious sandwiches or hash for breakfast the next day.
Frequently Asked Questions
How do I know when my prime rib is done?
Use an instant-read meat thermometer. For medium-rare, remove it from the oven when it hits 130°F internally and let it rest to reach 135°F.
Can I prepare the herb crust in advance?
Yes! You can mix the herb paste a day ahead and store it in the fridge. Let it come to room temperature before applying to the roast.
What size roast should I buy?
Plan for about 1 pound of bone-in prime rib per person. A 6-pound roast serves around 6 people.
Do I need to sear the roast before roasting?
No need! The high initial oven temperature gives it a perfect crust naturally.
Can I make this recipe without a bone-in roast?
Yes, a boneless rib roast works too—just reduce cooking time slightly and monitor temperature closely.
Should I use fresh or dried herbs?
Fresh herbs are recommended for their vibrant flavor and aroma, but dried herbs can be substituted in a pinch (use half the amount).
